EQUINOX

Although I haven't heard Pieces of Eight, I'd say this is the best Styx album of the albums through The Grand Illusion. The band continuously improved as it worked its way up to Equinox, then start getting bland with Crystal Ball and The Grand Illusion.

This album isn't very progressive, but it does have stronger rock songs than normal. This is also the last album with guitarist John Curulewski. He seemed to be a more interesting element in the band than his replacement after this album (Tommy Shaw).
